This project is a tiny pcb christmas tree with blinking leds. I found them on aliexpress (LEDS). They only require connecting to power supply and with a single battery you might even get away without using the resistors. Still, I decided to use 220Ohm resistors for the red, yellow and orange leds with 100Ohm for the blue ones. I hope that you will be able to buy those and maybe some other designs before chrismas this year at tindie.com.

Schematic

The schematic and PCB were both designed using Altium Designer and manufactured at JLCPCB. The PCB is panelized so that 4 of them take up almost the whole 100x100mm board space. Because of that I only paid $2 for 20 of them.
